Use when user says "help me understand", "teach me", "explain this", "learn about", "socratic", "feynman", "problem-based", "I don't understand", "confused about", "why does", or wants to truly grasp a concept.
Deep codebase exploration. Triggers: research, explore, investigate, understand, deep dive, current state.
Optimize SQL queries for performance with indexing strategies, query rewriting, and execution plan analysis. Use when queries are slow, optimizing database performance, or analyzing query execution.
Prisma ORM patterns - use for database access in Next.js, schema design, migrations, transactions, and relations

Maps and documents codebases of any size by orchestrating parallel subagents. Creates docs/CODEBASE_MAP.md with architecture, file purposes, dependencies, and navigation guides. Updates CLAUDE.md with a summary. Use when user says "map this codebase", "cartographer", "/cartographer", "create codebase map", "document the architecture", "understand this codebase", or when onboarding to a new project.
